13mm Paten: No. 104,225, dated .new 14, 1870.

...n.nn--P- The Schedule referred to in these Letters Patent and making pm cf the same iu the count-y of Westchester and the State of New York, have invented a new and useful Improvement in- Heaters; and I dohereby declare that the following is a full, clear, and exact descriptionthere of, which will-enable others skilled in the art to make and use the saine, rcferencebeiug had to the accompanying drawing forming part'ot' this speci-- fication. l

This invention relates to improvements in vheaters' for heating dwellings and the likebv means of'gold airreceived into a space between t'liejslll'A'f'the-.f combustionehamber and an outerfshcll, tobe heated and theuconveyed to the roomto he heated; and

It consists in an arranigementA in the saidV space' of heatngfplates, draught-regulatingplates, and a waterreservoir', whereby the ain-is heated and `mixed with the vapor rising from' water contained in the said res-` ervoir in a very' eilicieutmanner, the said arrangement being such that the heater may be very cheaply constructed. 1

f Figure 1 isa sectional elevation ofv'niy*irnprovedv heater, and o I Figure 2 is a horizontal section of the same.

Similar letters voi reference indicate corresponding 'A isthe cylinder, within `which the fire is to"j be, upon 'the grate B.

O is the exterior case, between which and the cyl.. iuder is the air-heating space D.

E represents heating-plates4 encircling the cylin- "der A,at suitable intervals above the cold-air-draught' regulating-plate F. They have holes, G, through them, to allow the airto pass upward slowly,the said holesbeing arrangedsothat the currents will not be direct, so that, in rising fronrone plate to another, the airj will impinge upon the `lower surfaces of the plates above, and thereby become heated as much as possible. 1 4

His a circular draught-regulating plate, arranged above plate F, toy .be turned on it for opening or closing the` passage '.lhe bottom plateIof the stove is provided with number Vof holes, K, and with a draught-regulating plate, L, above it, designed for use when the heater is set ou the door, (the legs being removed,) toreceivc the cold air fronrthe celarbclow, or through a cold- Aairconductor leading from tbeoutside of the build' f ingito theV bottom. l

M is 'a circular waiter-reservoir, suitably arranged rangementvof'draught-regulating,plates will he inodi fied, as.required, to admit of their free action.

' N represents small openings in the case C, with doors, for supplying water to the reservoirs.

O is thepipe for 'thc escape of the product of com'- bustion, and

P, the heated air-conductor. l Qis the opening for supplying the fuel to` the cylinder A.

' .It will be seenthat this arrangement is very cheap t and simple, and it is believed that it will be equally as eiiicient as any ,now in use. v

, Haviugdescribed my invention, i

I claimas new and desire to secure by'Letters Patent- The combination with'tlie cylinder lA and case C, ofthe perforated heating-plates E, the perforated bottom plate Lheatiiig and draught-regulating plate F, and regulating-plates H L, and the water-reservoir, all substantially as specified. o.

The` above specification of' myinvention signed by me this 9thfday of May,.`l870. g Y Y JOHN F. STILL.
